She has a femur again. All of the damage from the injury is healed instantly. The pain is gone. The dehydration and starvation and the rawness in her throat are all fixed, too.
She remembers.
She remembers a hundred or a thousand lifetimes of the desert, with nothing but herself and the sun and the sky and the sand and the heat, disassembling herself over and over again to make great structures of bone and sand and hair-ropes and sinew. She remembers cutting her own skin off to make jackets and pants and boots to protect herself from the endless burning. She remembers great epics written in the sand, mostly false but some of them true, embarrassing amounts of them written about how her friends would rescue her, even after she forgot which of the versions of her friends were the real ones, even after she forgot who she was. She remembers coming back to them, after a thousand years of centering meditation that taught her how to move things, how to fly. She remembers not being able to make any sense of them, not even the massive letters that spelled her name.
She remembers before all of this, before she built her empire of bones and blood, those first few panicked daysweeksyears of screaming and burning and desperately hoping that her friends would find her very soon. She remembers screaming until her throat was raw and dry. Remembers that she wasn't able to speak in more than tiny rasping sounds, not ever again.
She remembers Arda. She remembers Sunnydale. A tiny, tiny, tiny slice of her existence, but the place that all of the stories spring from. She doesn't know how many years it's been. Alex might be a hundred thousand years old now. He knew her for two. She was such a silly little girl, to think for so many years that he would come, that he would even remember her a thousand years later, but here he is anyway.
Alex?
